Percutaneous endoscopic gastrostomy in the elderly: complications (review)

Tube Feeding Patients With Dementia

As the population ages, the incidence of dementia increases. All types of dementia, whether they are reversible or irreversible, lead to loss of intellectual function and judgment, memory impairment, and personality changes. The skills to feed oneself, use eating utensils, and consume items recognized as food, thereby maintaining nutrition status, may be lost as dementia progresses. Reports indicate that nutrition status may be maintained when patients are hand fed, but this is labor intensive and therefore expensive. Feeding via a percutaneous endoscopic gastrostomy tube is often chosen as an acceptable alternative. Research indicates that there is little benefit in this population when aggressive nutrition support is instituted. Providing tube feeding to patients with dementia does not necessarily extend life, increase weight, or reduce the incidence of pressure ulcers or aspiration. There are many legal and ethical issues involved in the decision to place a feeding tube in demented patients. The primary issue in patients with dementia may be autonomy and the right of an individual to decide whether or not a tube should be placed at all. Legally, there is clear precedent that the courts see the insertion of a feeding tube as extraordinary care that the patient has the right to refuse. However, much of case law is derived from cases of patients who were in a persistent vegetative state. Advance directives help to determine what the patient would want for himself. Considering all the options before the patient can no longer make decisions is the most desirable course.

Percutaneous endoscopic gastrostomy in the dementia patient: helpful or hindering?

Percutaneous endoscopic gastrostomy (PEG) is a common technique performed worldwide. Recently, the use of PEG in the dementia patient with dysphagia for nutrition support has been called into question. Some reviews have reported no improvement in survival with PEG tubes in this population. Higaki and colleagues now present a large review of PEG tube placement in patients with dementia, which demonstrates a similar survival rate in patients without dementia receiving PEG tubes. The question of the utility of PEG tube placement for nutrition support in the dementia population requires an organized, prospective analysis to concretely answer the question.

Feeding alternatives in patients with dementia: examining the evidence

Percutaneous endoscopic gastrostomy tubes are being placed with increasing frequency in the United States among elderly patients with dementia. Health care providers believe there may be long-term benefits for enteral feeding in this population, yet previous study of this topic has failed to yield any convincing evidence to support this hypothesis. In this study, we review the evidence regarding outcomes for artificial enteral feeding in older individuals with dementia. We found that there is a lack of evidence supporting artificial feeding in the specific outcomes of survival, pressure ulcers, nutrition, and aspiration pneumonia. A brief discussion regarding hand feeding is included. The data suggest that hand feeding may be a viable alternative to tube feeding in elderly patients with dementia, although a direct comparison trial of the 2 interventions is lacking.

Healthcare costs associated with percutaneous endoscopic gastrostomy among older adults in a defined community

OBJECTIVES

The effectiveness of percutaneous endoscopic gastrostomy (PEG) in older adults remains controversial. Although prior studies have examined the safety of PEG and its impact on nutrition, there are limited data on the economic costs. The purpose of this study is to describe the healthcare costs associated with PEG tube feeding over 1 year.

DESIGN

Prospective cohort study.

SETTING

Small community of approximately 60,000 residents served by two hospital systems.

PARTICIPANTS

One hundred five (70%) of 150 patients age 60 and older receiving PEG over a 24-month period in the targeted community who permitted access to their medical records.

MEASUREMENTS

Patients were interviewed at baseline and every 2 months for 1 year to obtain information on use of enteral formula, complication rates, and health services use. We obtained inpatient charge data for all hospitalizations and PEG procedures for 1 year.

RESULTS

Censoring patients at death or 1 year post-PEG, the mean number of days of PEG tube feeding was 180 (range 5-365). The average cost for PEG tube feeding for this cohort of patients was $7,488 (median $3,691) in 1997 and 1998. The average daily cost of PEG tube feeding was $87.21 (median $33.50). The estimated cost of providing 1 year of feeding via PEG is $31,832 (median $12,227). The main components of this cost include the initial PEG procedure (29.4%), enteral formula (24.9%), and hospital charges for major complications (33.4%).

CONCLUSIONS

Direct charges associated with PEG tube feeding over 1 year are conservatively estimated at $31,832; there was considerable variation in charges because of the cost of rare but costly major complications. Also, feeding patients via PEG resulted in cost shifts in terms of the primary payor. The economic cost of PEG tube feeding is another consideration in decision making for long-term enteral feeding among older adults.

Nutrition in gastroenterology and hepatology

Nutritional issues, sometimes obvious and sometimes not so obvious, confront the primary care practitioner on a daily basis. Understanding the multi-disciplinary nature of nutrition science and clinical nutrition and having a basic understanding of gastrointestinal tract digestive and absorptive physiology can only help sort out the many issues involved. The general practitioner needs a core understanding of the principles of nutrition assessment.

Outcomes of percutaneous endoscopic gastrostomy among older adults in a community setting

OBJECTIVE

Percutaneous endoscopic gastrostomy (PEG) has become the preferred method to provide enteral tube feeding to older adults who have difficulty eating, but the impact of PEG on patient outcomes is poorly understood. The objective of this study was to describe changes in nutrition, functional status, and health-related quality of life among older adults receiving PEG.

DESIGN

A prospective cohort study.

SETTING

A small community of approximately 60,000 residents served by two hospital systems.

PARTICIPANTS

One hundred fifty patients aged 60 and older receiving PEG from one of the four gastroenterologists practicing in the targeted community.

MEASUREMENTS

Patients were assessed at baseline and every 2 months for 1 year to obtain clinical characteristics, process of care data, physical and cognitive function, subjective health status, nutritional status, complications, and mortality.

RESULTS

Over a 14-month period, 150 patients received PEG tubes in the targeted community; the mean age was 78.9. The most frequent indications for the PEG were stroke (40.7%), neurodegenerative disorders (34.7%), and cancer (13.3%). All measures of functional status, cognitive status, severity of illness, comorbidity, and quality of life demonstrated profound and life-threatening impairment; 30-day mortality was 22% and 1-year mortality was 50%. Among patients surviving 60 days or more, at least 70% had no significant improvement in functional, nutritional, or subjective health status. Serious complications were rare, but most patients experienced symptomatic problems that they attributed to the enteral tube feeding.

CONCLUSIONS

PEG tube feeding in severely and chronically ill older adults can be accomplished safely. However, there are important patient burdens associated with the PEG and there was limited evidence that the procedure improves functional, nutritional, or subjective health status in this cohort of older adults. The issues raised in this descriptive study provide impetus for a randomized trial of PEG tube feeding compared with alternative methods of patient care for older adults with difficulty eating.
